The diagnosis of asthma will be valid from 12 months prior to signing the informed consent
•Subjects with a positive prick test (higher papule diameter ≥ 5 mm) to a standardized extract of pollen from grasses (Phleum pratense, Holcus lanatus, Dactylis glomerata, Poa pratensis, Festuca elatior, Lolium perenne), or one of the components of the mixture and an olive extract.
•Specific IgE (CAP or Immulite) against a mixture of grasses or against one of the components of the mixture of grasses, preferably Phleum pratense and olive or one of the molecular components of allergenic sources with a value \> 3,5 KU / L.
•Women of childbearing age (from menarche) should submit a urine pregnancy test with a negative result at the time of joining the trial.
•Women of childbearing potential, and men participating in the trial, should commit to using an appropriate method of contraception. Medically acceptable methods of contraception are intrauterine devices placed at least 3 months in advance, surgical sterilization (for example, tubal ligation), barrier methods, or the use of oral contraceptives.
•Subjects capable of complying with the dosage regimen.
•Subjects who have a smartphone to record symptoms and medication.
•Subjects with a negative prick test to coestational pollens. In the case specific IgE is available, the result should be \<3,5 kU/L and without relevant symptomatology

Exclusion Criteria

•Subjects polysensitized to other aeroallergens with the exception of epithelia with occasional exposure and symptoms
•Subjects polysensitized to other aeroallergens with the exception non-seasonal pollens with grasses and olive
•Subjects who have received prior immunotherapy in the preceding 5 years to any aeroallergens.
•Subjects in which immunotherapy may be subject to an absolute general contraindication according to the criteria of the Immunotherapy Committee of the Spanish Society of Allergy and Clinical Immunology and the European Allergy and Clinical Immunology Immunotherapy Subcommittee.
•Subjects with severe or uncontrolled persistent asthma, with an FEV1 \<70% with respect to the reference value despite adequate pharmacological treatment at the time of inclusion in the trial. Likewise, subjects with intermittent or persistent rhinitis / rhinoconjunctivitis with severe symptoms in which the suspension of oral or systemic antihistamine treatment is contraindicated.
•Subjects who have previously presented a serious secondary reaction during the performance of diagnostic skin tests using the prick test.
•Subjects under treatment with ß-blockers.
•Clinically unstable subjects at the time of enrolment in the trial (acute asthma exacerbation, respiratory infection, feverish process, acute urticaria, etc.).
•Subjects with active chronic urticaria, severe dermographism, severe atopic dermatitis, sunburns, active psoriasis with lesions in areas where skin tests will be performed, or a history of hereditary angioedema.
